Sram APEX 1x Oval Chainring

What Our Gearhead® Experts Are Saying:

"This is the right oval ring for APEX 1, no adapters or compromises. It smooths power on sustained climbs and stays quiet even in muddy race conditions."

The Oval Premium Chainring for SRAM APEX 1 is engineered specifically for APEX 1 cranksets that use the asymmetric 110/4 BCD bolt pattern. We rely on it for cyclocross and gravel riding where a stable chainline, consistent engagement, and efficient power delivery are critical to maintaining speed and control. Designed by absoluteBLACK, it delivers oval performance without altering the simplicity of a 1x drivetrain.

Each chainring size is individually optimized with size-specific ovality and timing to smooth torque application through the pedal stroke. This reduces peak load at top dead center and improves traction during seated climbing and repeated accelerations. The narrow-wide tooth profile securely engages the chain, eliminating the need for a chainguide while maintaining quiet operation in muddy or dusty conditions.

Compatibility is limited strictly to SRAM APEX 1 cranks featuring the asymmetric 110/4 BCD interface, and original SRAM mounting bolts must be used for installation. This chainring is best suited for cyclocross racers and gravel riders running APEX 1 who want smoother pedaling, improved climbing control, and reliable chain retention from a drivetrain built for demanding mixed-terrain riding.
